Summary:
Store timestamps/packet numbers of recently received packets in AckState.
- The maximum number of packets stored is controlled by kMaxReceivedPktsTimestampsStored.
- The packet number of entries in the deque is guarenteed to increase
monotonically because an entry is only added for a received packet
if the packet number is greater than the packet number of the last
element in the deque (e.g., entries are not added for packets that
arrive out of order relative to previously received packets).

These are either no longer relevant, are unlikely to be done, or are spculative enough that they don't deserve code space.

Summary:
This implements the connection ID validation via transport parameters. Note we don't do anything with the retry transport parameter yet.
This will probably require further surgery to tests when we want the MVFST version to do this, but for now I'm punting on that test plumbing.
This retains support for h3-27.

Summary:
(1) Only read out the token if the parsing host is a client and the
token matches client's token
(2) More fallbacks to Stateless reset when parsing short header packet. The
only exception would be when we don't have 1-rtt cipher.

Summary:
Now we won't have a zero PTO and we will properly clear out the outstanding packets.
Note that this cipher dropping is not what the draft prescribes, instead dropping both the initial and handshake ciphers when we know 1-rtt communication is functioning.

Summary:
Don't use IOBufQueue for most operations in mvfst and use BufQueue instead. Since BufQueue did not support a splitAtMost, added it in instead.
The only place that we still use IOBufQueue is in crypto because fizz still requires it

Summary:
Allow the client to set zero-length id for itself.
If enabled, saves 8 bytes (if packet isn't padded to minimum).
However, will be disabled if connection migration is enabled.
Main changes include updating the short header parsing to pass
in the connection id length, since unlike long headers,
short header's dst conn id isn't preceeded by length.
Created a new `QuicClientTransportAfterStartTestBase` class
to move `testing::WithParamInterface<>` inheritance to subclasses.
(Only one parameter per test class).

Summary:
Prior to this we had an incorrect check for something being a stream frame. It technically should have worked for minimally encoded frame types, but would not work for a spec-incompliant frame type.
Instead of using a mask this makes it so each stream frame type is explicitly enumerated. This isn't as clean looking but is easier to validate as correct.
This also revealed some places where we were not correctly plumbing through the version for unit tests, so fixing those as a driveby.

Summary:
This introduce quic::Aead as a simple typedef to fizz::Aead and update the codebase to use quic::Aead . This should not impact the functionality of the code in any way.
This is a first step toward introducing an interface that is specific for mvfst so that mvfst can swap fizz for something else.
